PRANK PROJECT Side Panel Track Pants Price: 25,300 yen (tax included) Worn about 5 times. I'm hesitant to sell, so I'm listing it at this price. The waist is elastic and stretchy. The length is long, but there's a drawstring inside the piping line, so you can adjust the gathering and the length. It's made of a nylon, slightly rustling material, so it might be a little hot in mid-summer, but I think you can wear it regardless of the season.
